Incestuous Siblings

There is a silent, growing problem in our homes, amongst our children. It is incest. Many parents never know it is there. Others find out only after several of their children have been victimized.

Until recently, the prevailing belief was that adolescents do not commit sexual offenses of any serious consequence. As a result, the adolescent sexual offender has been neglected in prosecution, research, clinical literature, and treatment.

In 1981 the FBI Uniform Crime Reports state that juveniles were responsible for 20% of all our countries sexual offenses. A significant number of those reported were incestuous acts committed between siblings. These are only the reported crimes.

Since this is a silent crime and with the rise of easily obtained pornography and explicit TV shows, magazines, and Internet, it is feared that the percentage of incestuous sibling activity today, is incredibly high.

The following information was taken from three separate studies of intra-familial sexual offenders headed by Keith L. Kaufman, Ph.D., Associate Professor of Pediatrics and Psychology Children's Hospital and The Ohio State University

These facts tend to correlate with studies done on other sexual crimes on youth such as adult pedophiles.


Intra-familial offenders were defined as perpetrators whose primary sexual acts were victim(s) related to them or shared a home with them.

Personal Space-The area or space within arms distance of a person.

Grooming Behaviors - Behaviors used to gain positive sexual or favorable responses from younger siblings. The touching or caressing is used to get the victim used to their ever increasing and quickly becoming sexually oriented touching.

Graduated and Community-Based Sanctions for Juvenile Offenders Richard E. Redding, J.D., Ph.D. Many juvenile justice scholars agree that prison incarceration should be reserved only for a small number of very chronic or violent offenders, with graduated and community-based dispositions used for all other offenders.
